OSAS, observer scar assessment scale; VAS, visual analog scale; PSAS, patient scar assessment scale; PVSAS, patient vaginal scar assessment scale
Values are presented as mean ± standard deviation.
^a P values were calculated by paired t-test.
^b P values were calculated by Wilcoxon signed rank test.
^* Each scar characteristics of scar assessment scale has a 10-point scoring system ranges from lowest score 1 representing the situation of normal skin to highest score 10 representing largest difference from normal skin.
^† Each items graded on a 3-point scale ranging from 1 indicating minimal symptoms to 3 indicating maximum symptoms.
